Conditions at Moneglia in May
May: Downshift into Summer
May marks the real drop-off. Average swell falls to 0.5m (1.6ft), average period slips to 5.2s, and ideal offshore winds appear only 13% of the time. The wave rose is still dominated by SW at 37.2%, but the energy is heavily weighted toward the 0-0.5m and 0.5-1m classes. This is groveling territory - small, soft, low-tide lines for longboards and high-volume thrusters. The S and SSW fetch from the southern Ligurian Sea produces the same swell direction, but without strong winter lows, the period is not there. Water temperature rises to 17.8°C, and average air temps reach 17.3°C. Thermal sea breezes become a daily problem, so the best opportunity is at dawn when offshore north flow sometimes fights the developing onshore. If you need waves, May is about catching the leftover windswell after a final spring cold front.
